Abstract

The invention relates to a method for the hydrolytic polymerisation of epsi-caprolactam to polyamide-6, comprising a step (a) in which ring opening of part of the epsi-caprolactam to the corresponding amino caproic acid is effected in the presence of water and a step (b) in which polyaddition and polycondensation are effected under preferably anhydrous reaction conditions, in which at least one of the steps (a) and (b) is carried out in a reactor in which a self-renewing interface between the molten phase and the gas phase with a large surface/volume ratio of the molten phase is effected. The method is preferably effected in an horizontal scraped-surface reactor, since relatively strong mixing of the molten phase can be achieved in these and the molten phase is present in a thin layer, a large gas volume is present having a relatively high partial pressure of the water vapour and the thin layer is constantly renewed by shear forces. The method can be carried out in one reactor, preferably with several reaction zones, or with several reactors in series.
